## How to Convert Joules to Megajoules

To convert a joule measurement to a megajoule measurement, multiply the energy by the conversion ratio. One joule is equal to 1.0E-6 megajoules, so use this simple formula to convert:

The energy in megajoules is equal to the joules multiplied by 1.0E-6.

**For example,**here's how to convert 5 joules to megajoules using the formula above.

Joules and megajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Joules

The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*, for example 1 joule can be written as 1 J.

## Megajoules

One megajoule is equal to 1,000,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for 10^{9}. Megajoules can be abbreviated as *MJ*, for example 1 megajoule can be written as 1 MJ.
